[Build-common-hackers] Bug#628110: cdbs: Wrong install dir for python modules

[Olivier Aubert]

Package: cdbs
Version: 0.4.93
Severity: minor

When transitioning a package from python-support to dh_python2, dh_python2 generates the following warning:
W: dh_python2:96: Python 2.6 should install files in /usr/lib/python2.6/dist-packages/. Did you forget "--install-layout=deb"?

Indeed, modules are installed into /usr/lib/python2.6/site-packages

Adding the following line to debian/rules:
DEB_PYTHON_INSTALL_ARGS_ALL = --install-layout=deb
did not help. Moreover, it should be standard when using dh_python2.

It comes from the python-distutils.mk file that explicitly specifies

cdbs_expand_python_distutils_installdir = $(subst @PYTHONBINARY@,$1,$(or $(DEB_PYTHON_DISTUTILS_INSTALLDIR_SKEL),/usr/lib/@PYTHONBINARY@/site-packages/))

Changing it to specify dist-packages instead removes the warning. However, I am not sure about its validity wrt. other methods (pysupport and pycentral).
